aStatistical significance was found in group comparison between items in the Pearl River Delta and those outside the Pearl River Delta using the method of the chi-squared test. Age distribution of live-poultry workers from the Pearl River Delta was statistically different from that of those outside the Pearl River Delta (P = 0.02)
**P value was equal to or lower than 0.01. The chi-squared test was used in the statistical analysis. Gender distribution was statistically different for consumers living in the Pearl River Delta region and those outside the region (P = 0.002). Age distribution was statistically different for consumers living in the Pearl River Delta region and those living outside the region (P = 0.003). Income status and the status of being a Cantonese were statistically different between regions (both P values were lower than 0.001). Gender distribution was statistically different for live-poultry workers in the Pearl River Delta region and outside the region (P = 0.007). Live-poultry traders and poultry farm workers were statistically different between regions (P = 0.002)
